BSA B40 Oversize Intake Valve 1.56"

BSA B40 500cc Oversize Intake valve with 1.56" face dimension. 3.5" overall length.

Oversized Valves:

• Our oversized valves are flow tested for maximum performance
• Oversized valves can also be used to rejuvenate sunken valve seats while correcting valve geometry.
• Many of our oversized valve features relocated keeper locations to accommodate hi-lift racing cams and springs. This saves additional machining expense.

NOTE: Always be sure to check piston clearance before installing oversize valves.
